The Highways Agency has signed a £490m private finance initiative (PFI) deal to upgrade its communications network, which includes road messaging systems, CCTV cameras, roadside emergency phones and traffic monitoring systems.
The 10-year project has been awarded to the Fluor-led GeneSys Telecommunications consortium, and replaces a number of smaller contracts.
The new systems are designed to give operators more up-to-date information and pictures using internet-based technology.
Alcatel is part of the GeneSys consortium and has been awarded a contract worth £86m as part of the deal.
New cables to link roadside transmission stations will be installed on parts of the M3, M4 and M62 motorways in the first stage of the project.
